I have a question. I have to upgrade my environment to 6.5 but also change the way we do our VCSA management. We have 6 locations through out the country and each have one VCSA and external PSC. Now we going to split the sites in two- west coast and east coast. The PSC's is going to be hosted in a data center behind an F5 load balancer. Each site will have the VCSA HA systems hosted at each location point to the VIP of the F5. phew... now for the question.
Can I pre-build the two 6.5 PSC's in the datacenter and link them to a 6.0 PSC to sync? The objective is to have zero or very little downtime with this upgrade.
